Virginia City is a census-designated place (CDP) that is the county seat of Storey County, Nevada.〔(【引用サイトリンク】title=Profile for Virginia City, Nevada, NV )〕 It is part of the Reno–Sparks Metropolitan Statistical Area. Virginia City sprang up as a boomtown with the 1859 discovery of the Comstock Lode, the first major silver deposit discovery in the United States, and numerous mines were opened. At the city's peak of population in the mid-1860s, it had an estimated 25,000 residents. The mines' output declined after 1878, and the city declined. As of 2010 Census the population of Virginia City was about 855,〔(【引用サイトリンク】 title=Geographic Identifiers: 2010 Demographic Profile Data (G001): Virginia City CDP, Nevada )〕 with 4,000 living in Storey County. == History == Peter O'Riley and Patrick McLaughlin are credited with the discovery of the Comstock Lode. Henry P.T. Comstock's name was associated with the discovery through his own machinations.〔DeGroot〕 According to folklore, James Fennimore, "Old Virginny Finney," christened the town when he tripped and broke a bottle of whiskey at a saloon entrance in the northern section of Gold Hill, soon to become Virginia City.〔Smith, 7-14〕 In another story, the "Ophir Diggings", were named in honor of "Old Virginny" by the miners, in recognition of James Finney being "one of the first discoverers of that mining locality, and one of the most successful prospectors in that region." Finney "was the best judge of placer ground in Gold Canyon", locating the quartz footwall of the Ophir on 22 Feb. 1858, located the placers on Little Gold Hill on 28 Jan. 1859, and the placers below Ophir in 1857.〔Smith, G.H., 1943, The History of the Comstock Lode, 1850–1997, Reno: University of Nevada Press, ISBN 1888035048〕 After the discovery of the Comstock Lode in 1859, the town developed seemingly overnight on the eastern slopes of Mount Davidson, perched at a 6200-foot elevation. Below the town were dug intricate tunnels and shafts for silver mining. The Comstock Lode discovery and subsequent growth of Virginia City was unequaled by the history of other precious metal discoveries. By 1876 Nevada produced over half of all the precious metals in the United States.〔Powell〕 The Comstock produced silver and gold ore valued at hundreds of thousands of dollars. The wealth supported the Northern cause during the American Civil War and flooded the world monetary markets, resulting in economic changes. Virginia City's silver ore discoveries were not part of the California Gold Rush, which occurred 10 years before. At the time of the discovery of the Comstock Lode, silver was considered the monetary equal of gold, and all production was purchased by the federal government for use in coinage. In 1873, silver was demonetized by the government, in large part due to the flood of silver into international markets from the silver mines of Virginia City. Technical problems plagued the early mining efforts, requiring the development of new mining technology to support the challenge. German engineer Philip Deidesheimer created a timbering system for mining tunnels called square sets, which enabled the retrieval of huge amounts of silver ore in a safe manner.〔Smith, 23-4〕 Square set timbering, roots blowers, stamp mills, the Washoe Pan milling process, Cornish pumps, Burleigh machine drills, wire woven rope, miners’ safety cages and the safety clutch for those cages; even the Sutro tunnel all had a place in supporting the exploitation of the rich ore body. As technological advancements, these were used many times over in later mining applications. In 1876 one observer reported that in Virginia City, “every activity has to do with the mining, transportation, or reduction of silver ore, or the melting and assaying of silver bullion.”〔Powell, 239.〕 Like many cities and towns in Nevada, Virginia City was a mining boomtown; it developed virtually overnight as a result of miners rushing to the Comstock Lode silver strike of 1859. But, Virginia City far surpassed all others for its peak of population, technological advancements developed there, and for providing the population base upon which Nevada qualified for statehood. The riches of the Comstock Lode inspired men to hunt for silver mines throughout Nevada and other parts of the American West. Virginia City population increased from 4,000 in 1862 to over 15,000 in 1863. The city included gas and sewer lines, the one hundred room International Hotel with elevator, three theatres, the Maguire Opera House, four churches, and three daily newspapers. Many of the homes and buildings were made of brick.〔 With this center of wealth, many important local politicians and businessmen came from the mining camp. At its peak, Virginia City had a population of over 25,000 residents and was called the richest city in America.〔Rinella, p. 73〕 Dominated by San Francisco moneyed interests, Virginia City was heralded as the sophisticated interior partner of San Francisco. “San Francisco on the coast and Virginia City inland” became the mantra of west coast Victorian entrepreneurs.〔Collins, ''Mercantile Directory,'' 1864, 23.〕 Early Virginia City settlers were in large part the backwash from San Francisco and the California Gold Rush, ten years before. Mine owners who made a killing in the Comstock mines spent most of their wealth in San Francisco. A San Francisco stock market existed for the exploitation of Comstock mining. The Bank of California financed building the financial district of San Francisco with money from the Comstock mines. The influence of the Comstock lode rejuvenated what was the ragged little town of 1860 San Francisco. "Nearly all the profits of the Comstock were invested in San Francisco real estate and in the erection of fine buildings."〔Smith, 289〕 Thus, Virginia City built San Francisco. The Comstock success' measured in values of the time period totaled "about $400 million."〔Thomson, p.26〕〔Smith, 295〕 Mining and its attraction of population was the economic factor that caused the separation of Nevada territory from Utah, and later justified and supported Nevada statehood. The mining industry dominated Virginia City, making it an industrial center similar to those of the east coast. But the city retained some of its frontier flavor. The social history of the town has emphasized the high number of immigrants among its residents. Miners largely from Cornwall, England, where tin mines had been developed based on hard rock technology, flooded the Comstock. The new English immigrants were one of the largest ethnic groups. Many of the miners who came to the city were Cornish or Irish.〔Payton, Philip, ''Making Moonta: The Invention of Australia's Little Cornwall''〕 In 1870, Asians were 7.6% of the population, primarily Chinese workers who settled in many western towns after they had completed construction of the transcontinental railroad.〔(【引用サイトリンク】publisher=U.S. Census Bureau )〕 The Chinese filled niche markets, such as laundry workers and cooks. Through time, the numerous independent Comstock mines became consolidated under ownership of large monopolies. The “Bank Crowd,” dominated by William Sharon in Virginia City and William Ralston in San Francisco, financed the mines and mills of the Comstock until they had a virtual monopoly. By manipulating stock through rumors and false reports of mining wealth, some men made fortunes from the stocks of Virginia City’s mines. When it appeared the Comstock Lode was finished, the city's population declined sharply, with ten thousand leaving in 1864 and 1865. By the late 1860s, a group of Irish investors threatened the Bank Crowd’s control. John Mackay and partner James Fair began as common miners, working their way up to management positions in the mines. By purchasing stock in the mines, they realized financial independence. Their partners Flood and O’Brien stayed in San Francisco and speculated in stock. The Irish Big Four, as the men were called, eventually controlled the Consolidated Virginia mine where the “Big Bonanza” was discovered in 1873. The next few years were some of the most profitable on the Comstock, as the Bank Crowd lost control to the Irish Big Four. Population reached 25,000 in 1875.〔 Mining operations were hindered by the extreme temperatures in the mines caused by natural hot springs. In winter the miners would snowshoe to the mines and then have to descend to work in high temperatures. These harsh conditions contributed to a low life expectancy, and earned miners the nickname of "Hot Water Plugs." Adolph Sutro built the Sutro Tunnel to drain the hot spring waters to the valley below. But, by the time it was completed in 1879, the mines had substantially passed the intersection level, as their tunnels had been dug ever deeper.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Virginia City, Nevada」の詳細全文を読む スポンサード リンク
